An adjustable handlebar stem assembly includes a vertical tube with a head which has a toothed face. A stem includes two plates which are pivotably connected to the head and includes a clamping portion to clamp a handlebar thereto. A pawl member is pivotably located between the two plates and includes press end and an engaging portion on two ends thereof. The engaging portion has teeth removably engaged with the toothed face. A restriction rod extends through one of the two plates and is connected to a restriction member. A quick-release is pivotably engaged with a curved and recessed face of the pawl member. The quick-release includes a recess with which the restriction member is engaged. The quick-release cannot be pivoted when the restriction member is not moved and disengaged from the recess of the quick-release, so that the stem is not pivoted relative to the vertical tube.
